Six times ionized krypton (Kr VII) belongs to the ZnI isoelectronic sequence. The analysis of the atomic structure of this ion is important in astrophysical plasma research and recently the presence of Kr VII was detected in a white dwarf. In this work, new results about calculated lifetimes corresponding to energy levels of six times ionized krypton are reported. The studied configurations included the 4s2, 4p2, 4s4d, 4d2, 4s5s, 4s5d, 4p4f, 4f2, 4p5p, 4p5f, 4s6s, 4s6d, 3d94s24d and the 4s4p, 4p4d, 4s5p, 4s4f, 4s5f, 4p5s, 4p5d, 4s6p, 4s6f, 4d4f, 3d94s24p for both parities. Relativistic multiconfigurational Hartree-Fock, including core-polarization effects, and the energy matrix diagonalization were used in the calculations. A comparison of these results with the bibliography data was did.
